LPS-2337 introduced functionality to allow users to report or flag inappropriate, abusive, or objectionable content. Ever since Liferay Portal 5.2.3, it seems that there were hard-coded roles that these abuse emails would be directed to, for example, users with the Site Administrator and Site Owner roles.
Rather than limiting the abuse emails to be sent to Site Administrators or Site Owners, it would be extremely beneficial if there was the functionality to configure specific roles, groups, teams, or even users that would receive abuse emails per each site's portlet.
In terms of a business application for this functionality, let's say we have three teams that manage a site: blog team, message boards team, and general administrators. Let's say that someone posts an objectionable comment in the blog comments. It wouldn't make sense for just the Administrators to receive the abuse email. In this scenario, it would be helpful to configure it to the blog team. Same with flagged message board content. It wouldn't make sense to send it out to the owner/administrators of the site. It would make more sense to send it to a role that has control over the Message Boards portlet.
Improving this functionality should permit administrators to leave the functionality as is (send to specified roles that can be selected), or permit notifications to specific roles, users, teams and groups.
